Jim's dog weighs 18 pounds 10 ounces.
His cat weighs 6 pounds 3 ounces. How
many more ounces does Jim's dog weigh
than his cat?

12 Pounds and 7 Ounces

Step-by-step explanation:

18 10/16 - 6 3/16 = 12 Pounds and 7 Ounces

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)
